An analysis of film tropes—common storytelling elements seen in different movies—explores combinations of tropes that tend to co-occur in films, identifying patterns that could help inform development of new movies. Pablo García-Sánchez and Juan Merelo of the University of Granada, and Antonio Velez-Estevez and Manuel Cobo from the University of Cádiz, Spain present these findings in the open-access journal PLOS ONE on March 31, 2021.
